CT venography of the pelvis during CT pulmonary angiography does not improve the detection of VTE, says Dr. Charbel Ishak, lead author for this study. He asserts, "Using CT venography in the lower extremities without including the pelvis can decrease the population's radiation dose generated by CT usage."
In a retrospective review of 1,527 patients at the Nassau University Medical Center during a three-year period, only 0.3% (5 of 1,527) of patients presented with isolated pelvic VTE after pulmonary embolism was ruled out of the CT protocol.
Dr. Ishak believes that these results are promising for helping radiologists implement new protocols for pelvic examination and reducing further radiation in patients. He says, "Radiologists and technologists can eliminate pelvic imaging while acquiring only images of the lower extremities with CT venography, starting from groin to below the knee. We believe that by stopping the imaging of the pelvis, we can decrease patient radiation dose without significantly affecting the diagnosis of VTE."
Dr. Ishak will deliver a presentation on this study on Tuesday, May 3, 2011 at the 2011 ARRS Annual Meeting at the Hyatt Regency Chicago.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
